The new, farthest galaxy has been found by JWST, only 280 million years after the Big Bang
The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it's sensed light from a galaxy only 280 million years ...

'Cosmic joust': Astronomers observe pair of galaxies in deep-space battle
Astronomers have witnessed for the first time a violent cosmic collision in which one galaxy pierces another with intense radiation. Their results, published in Nature, show that this radiation dampens the wounded galaxy's ...

Could black holes be growing inside stars—silently and forever?
When people think of black holes, they imagine something dramatic: a star exploding in space, collapsing in on itself, and forming a cosmic monster that eats everything around it. But what if black holes didn't always begin ...
For galaxies forming stars, it's not about how much gas there is but where you find it
Researchers at the International Center for Radio Astronomy Research (ICRAR) made the discovery about galaxies by studying the gas distribution that helps create stars.

Einstein Probe detects a peculiar X-ray transient
An international team of astronomers using the Einstein Probe reports the discovery of a new peculiar fast-evolving X-transient. The newfound transient exhibits an unprecedented long-lasting X-ray emission. The finding was ...
The sun up close: Observations with new VTT camera technology deliver 8K image resolution
Large and complex sunspot groups characterize the surface of the dynamic sun during its activity cycle. A new camera system at the Vacuum Tower Telescope (VTT) at the Observatorio del Teide on Tenerife uses image restoration ...

Jupiter was formerly twice its current size and had a much stronger magnetic field, study says
Understanding Jupiter's early evolution helps illuminate the broader story of how our solar system developed its distinct structure. Jupiter's gravity, often called the "architect" of our solar system, played a critical role ...

Hubble captures distant galaxy's light bent into a partial Einstein ring
This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the galaxy was 5.5 billion light-years ...

Astronomers can classify satellites by watching how they block stars
The satellite population in low Earth orbit (LEO) is not an open book. While data on many satellites is public, others are shrouded in secrecy, and information is incomplete for others. New research shows how observers can ...

Exoplanet's companion found via orbital mechanics variations
Tracking exoplanets via orbital mechanics isn't easy. Plenty of variables could affect how a planet moves around its star, and determining which ones affect any given exoplanet requires a lot of data and a lot of modeling.

Multiwavelength observations investigate the variability of young star DR Tauri
Using various ground-based and space telescopes, an international team of astronomers has observed a highly variable young star known as DR Tauri. Results of the observational campaign, published May 12 on the arXiv preprint ...
The deepening mystery around the JWST's early galaxies
When the JWST came to life and began observations, one of its first jobs was to gaze back in time at the early universe. The Assembly of Galaxies is one of the space telescope's four main science themes, and when it observed ...
